Why not....their Somali waters?
Maybe a 50/50 split will be in our interest.
If you've got the power like Ethiopia, who lost a case about the border with Eritrea, you can just ignore it.
Somalia has no Navy, airforce or army.
Ethiopia is different Ethiopia has strong ties with the international community the isolated Eritrea is no match for Ethiopia diplomatically.
Somalia case is different if Somalia and hassan sheikh play their cards well and win the case. All they have to do is send Hawiye militia in the sea and terrorize the Kenyans and act like pirates , there is nothing the kenyans can do and the IC has no leg to stand on.
